Xenochilicola fulva Toro and Moldenke, 1979. An. Mus. Hist. Nat. Valparaíso 12: 148. Female. New synonymy. FIGURES. 4–9. Xenochilicola species. 4–6, Lateral habitus of: 4. X. mamigna; 5. X. diminuta; 6. X. haroldotoroi n. sp. 7–9, Metasoma in dorsal view of: 7. male, X. diminuta; 8, 9 female of X. diminuta. Top scale for Figs 4–6, bottom scale for Figs 7–9. Diagnosis. The metasomal colour pattern is variable in females (Figs. 8 and 9) but always mostly red, orange or yellowish whereas other species in the genus have the terga almost entirely black. The males are unique in having metasomal terga with yellow bands (Fig. 7) and S5 with a distinct, posteriorly directed, lateral process on each side (Fig. 14) whereas the other species have the posterior margin of S5 merely concave and hairy laterally. Mesoscutellum with dense punctures (i >d); irregularly punctate on mesoscutum (i~d on disk, i d); hypoepimeral area and metepisternum rugulose with sparse punctures; preepisternum and mesepisternum with denser punctures (i d); T1 irregularly punctate (i=0.5–3d on disc, i d. Basal area of propodeum reticulate (in some specimens with subparallel striae, not attaining posterior margin). Pubescence. Similar to that of male except as follows: apressed pubescence on paraocular area slightly sparser, hairs on hind leg scopa ~MOD; sternal scopa of long hairs on S1–S3 (~2.5 MOD); no lateral brushes of hairs on S5. Structure. As in male except as follows: Clypeus with shallow median longitudinal sulcus, apical margin of clypeus concave, clypeus projecting 0.8–0.9 of its length below lower margin of eyes; malar area very long, about twice as long as the width of mandible at base (2.0:1.1). OOC:IOC (1:2), UOD:LOD (5:3). Gena narrower than eye (1:2). Holotype of X. diminuta: CHILE, Santiago, Quebrada La Plata, 11.x.1996, colls. Schlinger and Irwin, male, in collection Toro (AMNH). Holotype of X. fulva: CHILE, Antofagasta, Taltal, 30.ix.1972, coll. J. Neff, female, in collection Toro (AMNH). Material Examined: (Fig. 13). Type series localities: CHILE, Región Metropolitana, Quebrada de La Plata and Región II, Antofagasta (Taltal).

A. Ugarte Peña (1 female). Región Metropolitana: Cerro Roble near Til–Til, 19.xi.2001, coll. L. Packer (1 female); same data but collected 17.xi.2001 (1 female, 1 male). These specimens are at the AMNH, Universidad Católica de Valparaíso, Chile or Packer collection at York University, Canada. Comments. Xenochilicola diminuta was described from four males. The female was described in the same paper, as X. fulva (known only from females). The collection and study of a larger sample of females and males taken together, in the same localities, allows us to synonymise X. fulva with X. diminuta Variation is as follows for the male: spot on malar space sometimes extending to the eye margin anteriorly and beyond the ventral margin of the eye posteriorly. Yellow metasomal bands variable on T3–T6: interrupted medially in some specimens, narrower than those on T1–T2, irregular in shape. Female with metasomal colour pattern variable in extent of pale background markings and also in colouration; yellow, amber, brown and red brown. The type of X. fulva has the base of T1 red brown but the terga are otherwise amber. In general, variation in colour pattern was not associated with geographic distribution. The junior author saw large numbers of males and females of this species on flowers of Cistanthe sp. (Portulacaceae), between the Pan American Highway and the town of Diego de Almagro, Región III, in October 2001.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
